Gonzalez said around 1:20 p.m. the children were reported missing by their grandmother. She told deputies she went to the store and when she returned, they were gone.

The man, identified by authorities Thursday night as 38-year-old Cimarron Yancey Wolfe, is believed to have abducted the children and brought them to another home in the 14000 block of Edgeboro Street.

Gonzalez said a different family member arrived at the home and saw the front door open. After checking inside, she looked outside and found the bodies of the man and children behind a shed in the backyard.

At this point, deputies are trying to figure out the relationships of the man to the children. Gonzalez said it appears Wolfe was the father of one of the children. He said both children share the same mother.

Investigators are also working to determine a motive in the shooting.

"This happens way too often and it's very sad and unfortunate that we still see situations like this occur. Our condolences go out to all of the families involved in this." said Gonzalez.
